Individual Ministerial Responsibility

Introduction

Individual ministerial responsibility is a foundational constitutional convention of the UK system of government. It holds that each minister is personally accountable to Parliament for the conduct of their department and for their own conduct as a minister. The convention operates alongside collective ministerial responsibility and together they form the core of ministerial accountability to Parliament. Individual responsibility serves as the primary mechanism through which Parliament holds the executive to account, requiring ministers to answer for the actions and omissions of their departments and to take personal responsibility when things go wrong.

The Conventional Framework

The convention of individual ministerial responsibility has two dimensions. Departmental responsibility requires ministers to account to Parliament for the policies, operations, and actions of their departments. Ministers must answer parliamentary questions, appear before select committees, provide information to Parliament, and ensure their departments implement legislation and government policy effectively. The ministerial account is given through oral and written parliamentary questions, departmental questions in the House of Commons, urgent questions, select committee appearances, and debates. The Ministerial Code codifies these obligations, requiring ministers to be “accountable to Parliament for the policies, decisions and actions of their departments and agencies.” The second dimension is personal responsibility: ministers are expected to resign if their personal conduct falls below the standards expected, or if serious failures occur in their department for which they are personally responsible.

The Resignation Convention

The convention that ministers should resign for serious errors has a long but inconsistent history. The leading case is the Crichel Down affair (1954), in which Sir Thomas Dugdale, the Minister of Agriculture, resigned after his department mishandled the disposal of land compulsorily acquired during the Second World War. Dugdale accepted constitutional responsibility for the actions of civil servants in his department, even though he had no personal knowledge of the errors. This established the principle that ministers are responsible for their departments—though the scope of this principle has since been narrowed. More recent resignations include Lord Carrington (Foreign Secretary) over the Argentine invasion of the Falkland Islands (1982) and David Blunkett (Home Secretary) over fast-tracking a visa application (2004). However, many instances of departmental failure have not resulted in resignation, including the Iraq War (2003) and the Windrush scandal (2018), suggesting the convention is applied inconsistently and depends heavily on political context.

Departmental Oversight

Ministers are responsible for the oversight of their departments, including the actions of civil servants and arm’s-length bodies. The Carltona principle (from Carltona Ltd v Commissioners of Works (1943)) provides that decisions taken by officials in a minister’s name are legally deemed to be the minister’s decisions, enabling the efficient administration of government departments. Ministers cannot, however, evade responsibility by delegating to officials. The Framework Document for each department sets out the respective responsibilities of the minister and the permanent secretary. The Accounting Officer system, under which the permanent secretary is personally responsible for the department’s financial management, creates a parallel accountability structure. The Public Accounts Committee and the National Audit Office scrutinise departmental expenditure. The Cabinet Secretary and the Permanent Secretaries group oversee the operation of government.

The Ministerial Code

The Ministerial Code (published by the Cabinet Office) is the authoritative statement of the standards expected of government ministers. It covers the principles of ministerial conduct, including integrity, propriety, objectivity, accountability, openness, honesty, and leadership. The Code requires ministers to ensure that no conflict of interest arises between their ministerial duties and their personal interests, to maintain the confidentiality of government business, to obey the law, and to uphold the civil service’s political impartiality. The Independent Adviser on Ministers’ Interests investigates alleged breaches of the Code and advises the Prime Minister. However, the Prime Minister has the final decision on whether a breach has occurred and what consequences follow, making enforcement a matter of political judgment. The Code has been updated periodically, most recently following the Greensill affair (2021) and the Partygate scandal (2022).

Civil Service Accountability

Individual ministerial responsibility intersects with the accountability of civil servants. Civil servants are accountable to their minister, not directly to Parliament. The Carltona principle means that legal responsibility rests with the minister, not the civil servant who made the decision. However, the Osmotherly Rules (published as Departmental Evidence and Response to Select Committees) govern how civil servants give evidence to select committees, providing that officials explain policy but not defend it—that is the minister’s role. The Civil Service Code requires civil servants to act with integrity, honesty, objectivity, and impartiality. Special advisers—temporary civil servants appointed by ministers on political grounds—operate under distinct rules set out in the Code of Conduct for Special Advisers, which limits their role to political assistance rather than civil service management.

The Osmotherly Rules

The Osmotherly Rules (formally Departmental Evidence and Response to Select Committees) provide guidance on the relationship between civil servants and select committees. They establish that civil servants appear before committees as witnesses on behalf of their ministers, not as independent officials. Civil servants may explain government policy and provide factual information but must not express personal opinions or challenge government policy. The Rules have been criticised for limiting parliamentary scrutiny, particularly in relation to sensitive matters where ministers may restrict the information that officials can provide. The Public Administration and Constitutional Affairs Committee has recommended reform of the Rules to enhance transparency. The House of Commons Liaison Committee has also called for greater direct accountability of senior civil servants to Parliament.

Conclusion

Individual ministerial responsibility remains a central convention of the UK constitution, providing the primary mechanism for holding ministers to account for their conduct and for the performance of their departments. The convention has, however, become increasingly contested. The expectation that ministers should resign for departmental failings is applied inconsistently, and the growth of prime ministerial power has reduced the capacity of individual ministers to resist pressure to remain in office. The Ministerial Code provides a codified framework, but its enforcement depends on the political judgment of the Prime Minister. The relationship between ministerial responsibility and civil service accountability continues to evolve, with select committees increasingly seeking direct accountability from senior officials. The convention remains indispensable as a principle, even as its practical application is shaped by political calculation and constitutional change.
